the.com/hyoid

the only bone that touches nothing else, floating in your throat like a secret

means The U-shaped bone in the neck that supports the tongue and anchors the muscles of swallowing and speech, held in place only by muscle and ligament rather than joined to other bones.

from From Greek 'hyoeides,' meaning 'shaped like the letter upsilon' (Υ) — built from 'hy-' (the letter) plus 'eidos' (form, shape). Anatomists named it for its resemblance to that little Greek 'u,' a fitting tag for a bone that hangs in the throat like a written character no other bone will touch.
